Embodiment Construction
[0016] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0017] The invention discloses a stamping side flanging die, see Figure 1 to Figure 3 , including an upper die, a lower die, a binder core 1, an upper flanging insert 2 and a lower flanging insert 3.
[0018] The pressing core 1 is arranged on the upper mold and protrudes downward, and the side of the pressing core 1 facing the lower mold forms a first inclined surface. The first inclined surface cooperates with the second inclined surface on the turn-down insert 3 to drive the turn-down insert 3 to move. The pressing core 1 also has ...

The invention discloses a stamping side flanging die. The die comprises an upper die and a lower die, and further comprises a material pressing core, an upper flanging insert, a lower flanging insert,wherein the material pressing core is arranged on the upper die and protrudes downwards, and a first inclined surface is formed on one side, facing the lower die, of the material pressing core; the upper flanging insert is fixedly arranged on the upper die; the lower flanging insert is arranged on the lower die in a sliding mode, the top part of the lower flanging insert is provided with a secondinclined surface, the second inclined surface is matched with the first inclined surface and slides towards a first direction under the driving of the material pressing core; and the limiting position of sliding towards the first direction is that the lower flanging insert presses against the upper flanging insert to realize flanging of a workpiece. According to the stamping side flanging die, the material pressing core plays a role in driving the die block at the same time and in matched with the lower flanging insert to directly enable the lower flanging insert to slide, the space of a wedge pulley is omitted, so that the size of the stamping side flanging die is overally reduced, the travel distance is saved, the preparation cost is reduced, and the preparation efficiency is improved.
Description
technical field [0001] The invention relates to a stamping side flanging die. Background technique [0002] At present, due to the need to control the cost of automobile stamping dies, basically every pair of dies is a composite process in process planning. Due to the inheritance of equipment required by various processes, this kind of stamping die is often referred to as huge and long stamping stroke distance , which affects the cost and efficiency of mold preparation. Contents of the invention [0003] The purpose of the present invention is to provide a stamping side flanging die, which solves the problems of high cost, large volume and low manufacturing efficiency of the composite process die in the prior art. [0004] The stamping side flanging die of the present invention includes an upper die and a lower die, and further includes: a pressing core, which is arranged on the upper die and protrudes downward, and the pressing core is formed on one side facing the lower...
